ROTARY ENGINE.

SPECIFICATION `forming part of LettersrPatent No. 239,953, dated April 12, 1881.

A Application filed August 30, 1879.

To all whom it may concern:

Be it known that we, EMANUEL HAUSE and FRANKLIN B. GRANGER, of' Somerset, in the county of Somerset and State ofPennsylvania, have invented certain new and useful Improvementsin Rotary Engines; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to theaccompanyingdrawin gs, which form a part of this specication.

Fignrel is a perspective view. Fig. 2 is a side view, the covering-plate of the engine having been removed. Fig. 3 is a longitudinal sectional view of the engine.

Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to rotaryengines 5 and it consists in certain improvements in the construction of the same,which will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, A a-nd B represent the furnace and boiler, which form the body of our improved engine, and which are supported upon the wheels C C' D D by spindles E E and by the .front axle, F, which latteris pivoted under the front end of the boiler.

Upon the furnaceAis secured the casing Gr of the engine. Said casing, which is approximately cylindrical in shape, carries on top the valve-chamber H.

a bracket projecting upwardly from the topof` the furnace.

Upon shaft J, within recess I, is formed or secured a bulge or disk, L, fitting between the sides of the casin g and against the top of the recess. .Transversely in said disk, and longitud-inally with the shaft J, is formed a slot, M, to accommodate the sliding plate N. The main shaft, it will be observed, has its bearings at such a point in the elliptical case that the slidingplate shall lit within the sides of the latter at any position occupied bythe rotating shaft.

Projecting upwardly from the recessI is a small transverse recess, Q, in-which is fitted a packing-strip, It, forced by coiled springs down against the disk L.

In the upper part of casing G, above the recess I, and centrally under the valve-chamber, with which it communicates through a channel, T, is formed the exhaust-chamber U.

V W are the steam-entrances, which are located respectively in front and rear of the channel T,and which are connected by channels X X with the recess I on opposite sides of the main shaft. A valve, Y, sliding longitudinally in the valve-chamber is of sufficient size to cover at the same time the opening T and either one ofthe steam-entrances, a recess, Z, in the under side of said valve serv ing to form a connection. between .the opening T and the steamentrance, covered at the time by the valve.

The valve-chamber H is provided with a horizontal partition, A', having a single central opening or steam-entrance, B', serving to connect the upper compartment, D', with'the lower, E'. A valve, F', sliding longitudinally iu the compartment D' of the valve-chamber, may be adjusted, in t-he manner hereinafter to be described, over the said opening B', thereby cutting off the steam.

YIn a bracket, G', projecting rearwardly from the rear side of the casing G, is formed a bearing for a crank-lever, H', the upper extremity of which is pivoted to the outer end of the operating-rod I' of valve Y, which extends out through a` suitable opening in the rear end of the valve-chamber. The lower end of lever H' forms ai'handle, within convenient reach of the attendant, whose station is behind the body of the machine. It will be observed that by shifting the position of the lever the valve Y may be adjusted over either one of the openings V W, which is thus connected with the exhaust-chamber.

The operating-rod F" of the valve F' eX- tends through au opening in the forward end of the valve-chamber, and its outer extremity is pivoted to a vertical lever, I", secured to a transverse horizontal shaft, J', having its bearings in a bracket, K', upon the front side IOO of casing G. The end of shaft J' is provided with a downwardly-projecting crank or lever, L', having a curved or segmental slot,M', in which is fitted 'a slide, N'. Pivoted to one end of said slide is a link, O', connecting it with the forward end of a lever, P', pivoted to the side of the casing, lthe rear end of which lever is confined within a guide-slot, Q', and within reach of the attendant. To the other end of the slide N' is pivotedl the forward end of a bracket, R', forming part of a sectional ring or band, S', adjusted around ay grooved eccentric-disk, T', secured upon the outer end of the main shaft J.

When the machineis in operation the valve F' is continually reciprocated by the mechanism described, the length of stroke being regulated by raising or lowering lever P'. This is in order to cause the machine to be operated to a greater or less extent by the expansion of steam, by which considerable savin gis effected.

Upon the opposite end of the main shaft is keyed a sliding clutch-collar, U', operated by a forked lever, V', pivoted in a suitably-arranged bracket, W', within reach of the attendant. The clutch-collar U' is adapted to engage a clutch, X', upon a pinion, Y', which is loose upon the shaft. Pinion Y' engages, either direct or through an intermediate cogwheel, Z', a gear-wheel, A2, upon the drivewheel C, towhich motion is in this manner transmittedi The operation of the engine is as follows: A pipe, B2, conducts the steam from the boiler tothe upper compartment of valve-chamber H, from which, supposing the opening B' to be unobstructed, it passes into the lower coinpartment, E'. Now, supposing the openings T W to be covered (and connected) by the valve Y, the steam will pass through the opening V and channel X connected with said opening, into one side of the cylinder, where it strikes one side of the sliding plate N, it being excluded from the other side by the arrangementof packing-strips, above described. The pressure upon plate N rotates the shaft until the ends of the plate reach the respective openings o f channels X X, which, of course, should be so arranged as to be passed at the same time by the ends of the plate. As soon as the said openings are passed the steam conined in the chamber bounded by plate N and the cylinder-walls escapes through channel Xin the rear of the case-openin g W, under valve Y, through channel T, and into the eX- haust-chamber, from which it escapes through a suitably-arranged pipe, C2, or is conducted to a condenser. At the same time steam is admitted from opening V to the opposite side of plate N, thereby continuing the operation of the engine.

To reverse the engine it is only necessary to change the position of valve Y so as to cover and connect the openings T V and admit the steam through opening W. To stop the engine the valve F' is operated by the mechanism above described in such manner as to place it over the opening B', thus cutting off the steam.

In the sides of the casing Gr, around the main shaft and surrounding the operatingrods of the valvesYF', we adjust suitable packing-boxes D2, by which steam-tight joints are formed.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of our improved engine will be readily understood by those skilled in the 'art to which it appertains. It :is simple, powerful, durable, and economical of steam. Great speed of the main shaft may be attained.

We are aware thatit is old, broadly, to mount upon and drive the transporting-wheels of anengine by a rotary engine; and, further, that it is old in a rotary engine to employ an eccen- P', lever H', the eccentric T', eccentric-strap S',

and connecting-link R', substantially as and for the purpose set forth.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.
